tropinone were fed to transformed root cultures of Nicotianarustica and/or a Brugmansia candida × aurea hybrid. These cultures were made by the transformation of the relevant plant species with Agrobacterium rhizogenes . A number of the metabolites, notably those showing a relatively modest alteration in the N -alkyl substituent, were metabolized in vivo to form homologues of the normal alkaloids biosynthesized
摘要 将一系列 N-甲基腐胺和托品酮的类似物喂入转化的 Nicotiana rustica 和/或 Brugmansia candida × aurea 杂种的根培养物。这些培养物是通过用发根农杆菌转化相关植物物种而制成的。许多代谢物,特别是那些在 N-烷基取代基中表现出相对温和改变的代谢物,在体内代谢形成由这些根生物合成的正常生物碱的同系物。这些产品通过 GC/MS 进行鉴定并与一些合成参考材料进行比较。N-烷基取代基大小发生重大变化的类似物根本没有代谢。在 N. rustica 培养物中,以 1 mM 喂食的类似物显着影响了正常生物碱的分布,在存在 N-n-丙基腐胺的情况下,发现尼古丁最多减少 4 倍。吡咯烷系列和哌啶系列的生物碱之间的比例也受到影响。相比之下,念珠菌×金黄色混合培养物中 1 mM 类似物的存在不会抑制或显着干扰正常生物碱谱的积累。讨论了使用这些培养物从简单的前体制造复杂的新产品的潜力。

achieved from beta-chloroaldehyde 3 in 4 and 5 steps, respectively, with an overall yield of 25-28%. [(18)F]Fluoroethylamine was prepared by heating N-[2-(toluene-4-sulfonyloxy)ethyl]phthalimide with [(18)F]fluoride ion in acetonitrile. [(18)F]1 was obtained by slow distillation under argon of [(18) F]FCH2CH2NH2 into amine 10 that was pre-treated with triphosgene at 0-5 °C. The total time required for
